One problem related to radiator has been reported for the 1998 Mitsubishi Mirage. The most recently reported issues are listed below.
My Mirage has less than 72,000 miles on it. Without symptoms or warning, the car overheated and destroyed two head gaskets and possibly broke the plate. That's catasrophic damage! it's been well maintained and hardly driven. At less than 72,000 miles it will cost more to repair than it's worth. There was no indication whatsoever! it just died on the freeway, going 70 miles an hour. The radiator worked perfectly! of course Mitsubishi just tried tov sell me a new one. They could not have cared less.
